I agree with your opinion that it is invasive if you don't want it to grow
it.  How much degree you can change the local ecosystem to return back to
original pure-ecosystem.  I'm wondering it is
really needed to return back to a perfect original ecosystem?  A certain
compromise can be acceptable?  This is a micro-climate area.  Another
section of city is sunny and warmer which reflects
different vegetation. Global-warming is changing or reforming ecosystem.
Some scientists say that birds are moving toward cooler area, north.

I was pointed as a chair of Rotary Club's Wildflower (or Native Plants)
Program for the 61 acre hill top property in the heart of S.F. city in Dec.
It is covered by many invasive (?) eucalyptus trees, ivies, Himalayan
blackberries and many south African native plants.  Eucalyptus was welcome
here in California over 100 year before as a quick growing practical
windbreak and an exotic ornamental plant but now they are treated as an
enemy to inflame wildfires.  My favorite nursery in San Diego did not sell
Eucalyptus plants anymore.
The 61 acre open space reserve has many lime color ivy looking vines with
yellow flowers (I do not know the name).  I thought they were beautiful and
they can be easily pulled out, not like blackberries and ivies.
An independent volunteer's group is working to remove non-native plants for
years.  Their rule is so strict that 100% of not-native plants have to be
removed.  From my plant lover's point of view, they do not have any
affection toward plants.
